What is the box strategy in math?

The box method is a strategy for multiplying large numbers. It is an alternative to the standard algorithm for multiplication. The box method is based on an area array representation of multiplication. An array is proportional to the size of the numbers being multiplied.

How do you do box method?

The steps to use the box method are these:

1. Draw a two-by-two grid.
2. Write the first term in the upper left and the last term in the lower right.
3. Multiply the first and last terms together.
4. Find the factors from your multiplication.
5. Write this pair down in the remaining empty boxes.

How do you teach the box method?

Here’s how the “box method” works:

1. First you divide the larger number into its separate parts. Here, 23 becomes 20 and 3.
2. Next, you multiply each separate part — 20 x 7 and 3 x 7.
3. Finally, you add all the products together. 140 + 21 equals 161, the product of 23 x 7.

How do you multiply in China?

The Chinese Method, or stick method, of multiplication involves properly placing and crossing sticks. You simply lay out sticks consistent with the place values of the digits being multiplied. Then, you count the places where the sticks cross.

What are factors of 36?

Factors of 36 = 1, 2, 3, 4, 6, 9, 12, 18, and 36.

How do you find the product using the box method?

To multiply two numbers using the box method, make a table with the place values of the first factor along the top and the place values of the second factor down the left. Multiply the place values and enter their products in the table. Simplify the table. Sum each row of the table.

Why are Chinese better at math?

Chinese is better for math, research shows “The digit system is very simple in Chinese,” Leung says, “making at least arithmetic very easy to learn.” Researchers of early childhood education have found that the way a language describes numbers can affect how quickly children do sums. Take the number 11, for example.

What is the box method in math?

The box method in math is an alternative to traditional multiplication that has many steps and can cause many mistakes. The box method helps to simplify the process of multiplying two or more digits. How do you multiply using the box method?

What is the Chinese multiplication method?

Chinese Multiplication Method. The Chinese Method, also known as the stick multiplication method, uses sticks to solve multiplication problems. Look at Diagram One. First, Devon laid sticks beginning on the bottom left for the number 21. He put 2 red sticks for the tens place and 1 black stick for the ones place.

How do you multiply using the box method?

To multiply using the box method, first, write each number in expanded form. Then create a box that is the size of the number of digits for each number being multiplied. Next, fill in the box by multiplying the numbers that correspond to each row and column. Finally, all of the numbers inside the box to get the final answer.

How did the Chinese count numbers?

The Chinese interestingly used a different method in which sticks were used to represent the digits of each number and then the intersections of those sticks were counted in a specific way in order to get the correct product. Let’s look at one example below. Example 1:
